Firefox: 46 features you might not know about

Ever since the release of Firefox 3 we’ve been doing a lot of work to add new capabilities for web developers. We thought it would be worth it to make a post that actually listed all of the features that we knew about and people might not know about. This contains everything that we’ve done over the last three releases or so, but calls out stuff that’s new in 3.6.

Most of these are Gecko features rather than Firefox-only features, aren’t they? So:
– Which value of x should I watch for in the rv:1.9.x part of (let’s say) a SeaMonkey User-Agent string for the features mentioned above as ‘new in Fx 3.6’?
– Some of these have been present for quite some time, e.g., I have a book about CSS here, which documents -moz-border-radius as ‘present since Netscape 6’. I wonder why it hasn’t yet become part of ‘official’ CSS. Oh, well, I suppose that’s how slowly standards evolve.

I think there is problem with DNS prefetching and CSS fetching in FF 3.6. I regularly get “server not found” error. The sites load after refreshing the browser. But the problem is not over yet. The browser doesn’t fetch style sheet at all. I could only see page without any style. The site would load normally if I refresh it again.
